Category Labels Induce Boundary-Dependent Perceptual Warping in Learned Speech Categories
Swan, Kristen; Myers, Emily
Second Language Research, v29 n4 p391-411 Oct 2013
Adults tend to perceive speech sounds from their native language as members of distinct and stable categories; however, they fail to perceive differences between many non-native speech sounds without a great deal of training. The present study investigates the effects of categorization training on adults' ability to discriminate non-native phonetic contrasts. It was hypothesized that only individuals who successfully learned the appropriate categories would show selective improvements in discriminating between-category contrasts. Participants were trained to categorize progressively narrow phonetic contrasts across one of two non-native boundaries, with discrimination pre- and post-tests completed to measure the effects of training on participants' perceptual sensitivity. Results suggest that changes in adults' ability to discriminate a non-native contrast depend on their successful learning of the relevant category structure. Furthermore, post-training identification functions show that changes in perceptual categories specifically correspond to their relative placement of the category boundary. Taken together, these results indicate that learning to assign category labels to a non-native speech continuum is sufficient to induce discontinuous perception of between- versus within-category contrasts.
